Page 30 Operating Instructions
• In an UltiMate 3000 system, some components are made of PEEK. This polymer has
superb chemical resistance to most organic solvents. However, it tends to swell when in
contact with trichlormethane (CHCl
3
), dimethyl sulfoxide (DMSO), or tetrahydrofuran
(THF). In addition, it is attacked by concentrated acids, such as, sulfuric acid and nitric
acid or a mixture of hexane, ethyl acetate, and methanol. In both cases, capillaries may
start leaking or they can burst. Swelling or attack by concentrated acids is not a problem
with brief flushing procedures.
• Before switching from buffer to organic solution, rinse the system thoroughly with
deionized water.
• When switching to another solvent, ensure that the new solvent is miscible with the one
contained in the system. Otherwise, for example, the pump can be damaged by
flocculation.
• After operation, rinse out buffers and solutions that form peroxides.
Important: Neither recycle the solvent nor use methanol from aluminum
reservoirs. This may impair the performance of the seals.
Important: Thermo Fisher Scientific déconseille de recycler les solvants. Ceci
peut nuire aux performances des joints.
